RESUMO
There is lack of studies assessing the preference of Indian patients for integration of homeopathy into standard therapy settings. The objectives of this study were to examine the knowledge, attitudes, and practice of homeopathy among Indian patients already availing homeopathy treatment and its integration into mainstream healthcare. A cross-sectional survey was conducted among adult patients attending the out-patients of the four government homeopathic hospitals in West Bengal, India. A self-administered 24-items questionnaire in local vernacular Bengali was developed and administered to the patients. A total of 1352 patients' responses were included in the current analysis. 40% patients thought that homeopathic medicines can be used along with standard therapy. 32.5% thought that homeopathic medicines might cause side effects, while only 13.3% believed that those might interact with other medications. Patients' knowledge ranged between 25.1 and 76.5% regarding regulations of practicing and safety of homeopathic medicine in India and abroad; while positive attitude towards the same ranged between 25.4 and 88.5%. 88.6% of the patients had favorable attitude toward integrated services. 68.2% of the patients used homeopathic medicines in any acute or chronic illness for themselves and 76.6% for their children. Preference for integrated services was significantly associated with better knowledge (P = 0.002), positive attitudes toward safety and regulations (P < 0.0001), and integration (P < 0.0001), but not with the level of practice (P = 0.515). A favorable attitude toward integrating homeopathy into conventional healthcare settings was obtained among the patients attending the homeopathic hospitals in West Bengal, India.
RESUMO
We examined atomic force microscopy (AFM) and lateral force microscopy (LFM) images of human, avian, reptilian, amphibian, and piscine erythrocytes to determine whether the general pattern of erythrocyte membrane architecture has been largely conserved in the course of phylogenetic evolution or relatively minor modifications have taken place. The general pattern of the cell surface structure is indeed very similar among the phyla examined. The surface features include a number of blebs or globular structures and hole-like depressions. Such features are particularly clear in fish (Heteropneustes sp.), in which globular blebs are arranged in tiers around the depressions. The same pattern is found in the other phyla, although the sizes of the blebs and depressions vary. The depressions are approximately 340 and approximately 100 nm in diameter in chickens and fish, respectively, and are smaller in other phyla. The images of human erythrocytes presented here show holes more clearly than the images obtained by Zhang et al. (Scanning Electron Microsc., 1995; 9:981-989), who showed for the first time the highly uneven surface of these cells. The globules range in size from approximately 50-150 nm in diameter. These nanostructures have a width of approximately 333-1,000 atoms, assuming that the average dimension of an atom is 1.5 A. The size range of the holes is approximately 40-432 nm (equivalent to a width of approximately 266-2880 atoms). LFM images, which take into account the lateral component of the force, represent the variation of surface friction (roughness) on the erythrocyte surface. This is very clear in the toad images, which show well-ordered strata that have not been revealed in ordinary AFM images.
